[net.micro.apple] shift-key mod for Apple ][+

rupp@tetra.UUCP (William L. Rupp) (09/24/85)

This is in response to a question about shift-key modification for the Apple
][+.  I have used two different gadgets to do this, and they both involved
connecting a clip to a pin under the keyboard at one end, and to the game
I/O port on the other.  The first unit, from Micromax, had a 16 pin chip-
like device that plugged into the game I/O port.  It was designed so that
another connector could then be plugged on top of it.  Therefore you would
have no conflict with joysticks, etc.

The second device, which is in my current Apple ][+, has, instead of the
16-pin business, a second clip, which itself attaches to one of the pins
on a game connector (I happen to have one of those game I/O extenders which
allows you to hook up your joystick easily outside the case.)  I prefer this
one, since I did not have to unplug my game port extender (I hate removing
and inserting chips!!!) to make it work.  I purchased this device for a very
reasonable price from a local Apple dealer.  Sorry, I do not remember the 
name of the product.  

It is also possible to do a hardware modification which requires some
motherboard soldering, or suchlike.  I myself avoid this kind of remedy like
the proverbial.  Since these other devices are for sale, you probably will  
want to do likewise.

Although I never did it (having a 2e instead of a 2+) a friend
of mine discovered that the 2+ keyboard PCB uses a keyboard
encoder chip with provisions for lower case - it just isn't
hooked up.  Furthermore, a standard slide switch can be installed
in HOLES ALREADY PROVIDED ON THE PCB that gives either standard
Apple or upper/lower case with the keyboard shift key.  He chose
to mount the switch on the front panel anyway for convenience.

The problem is in the Apple monitor, which masks any lower case
to upper case.  The fix is simple if you put the monitor in the
language card RAM.
